ESP32 Capacitive Soil Sensor Read Problem

I read all topics

Not quite!

PLEASE HELP! ESP32 not reading analog sensors

Note: ADC2 pins cannot be used when Wi-Fi is used. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead, that should solve your problem. Pete.

GPIO26 is an ADC2 pin, and shouldn’t be used as an analogue input when using WiFi.
